Ingersoll-Rand Trane TR15REG-DB is an electrical device used to connect electrical loads to either utility (normal) power source or an emergency power source. It is typically used to automatically switch electrical loads to a standby generator in the event of a power outage. Some of its capabilities include:

Automatic transfer: The switch can automatically transfer loads between the main power source and the generator when the main power fails.
Voltage monitoring: The switch can monitor the voltage of the main power source and the generator to ensure that the loads are receiving a stable voltage.

Automatic transfer: The switch can automatically transfer loads between the main power source and the generator when the main power fails.

Preface

The Automatic Transfer Switch (hereafter referred to as ATS) uses world-famous ATS or AC Contactors as

the main switches, and are manufactured from advanced and closely-controlled production processes. It is

combined with all our automatic generators to form a complete and thorough Automatic Transfer System.

The DKG-173 Transfer Controller is installed inside the ATS, which applies to three phase or single phase

systems with phase voltage of 220v AC. Pluggable connectors are connected with external connections, which

make the maintenance, inspection, or replacement easy and convenient.

We have 125A single phase ATS, 125A three phase ATS, and 200A single phase ATS for your different needs in

various conditions.

Functions

ATS has control functions (such as generator start-up delay, mains restore delay and voltage

detection, etc.). When the ATS is connected to automatic generators, the generator's control

box will send the transfer signal in order to transfer loads automatically. It can operate with our automatic

control systems or other brands that have remote-start self-control functions which are simple and economic.

Important Safety Instructions

• Remove all jewelry (such as rings, watches, bracelets, etc.) before working on this equipment.

• If work must be done on this equipment while standing on metal or concrete, place insulative mats over a dry

wood platform. Work on this equipment only while standing on insulative mats.

• Never work on this equipment while physically or mentally fatigued.

• Keep the transfer switch enclosure door closed and bolted at all times. Only qualied personnel should be

permitted access to the switch interior.

Equipment Description

The automatic transfer switch is used for transferring electrical load from a UTILITY (NORMAL) power source

to an EMERGENCY (STANDBY) power source.

Mounting

• This model automatic transfer switch is designed for use only with Trane home standby generator sets.

• Install the transfer switch as close as possible to the electrical loads that are to be connected to it. Mount the

switch vertically to a rigid supporting structure.

• To prevent switch distortion, level all mounting points. If necessary, use washers behind mounting holes to

level the unit.

Connecting Power Source and Load Line

• Wiring diagrams and electrical schematics are provided in this manual.

• Before connecting wiring cables to terminals, remove any surface oxides from the cable ends with a wire

brush. All power cables should enter the switch next to transfer mechanism terminals. If ALUMINUM

conductors are used, apply corrosion inhibitor to conductors.

• Tighten terminal lugs to the torque values as noted on the decal located on the inside of the door. After

tightening terminal lugs, carefully wipe away any excess corrosion inhibitor.

18-SG01D1-1A-EN

Operation Instructions

Automatic Mode

1. Move the control switch of the ATS Control Panel on the AUTO position, the control mode of the generator

is "AUTO".

2. When mains are on load, the indicators "Mains Available" and "Mains On Load" will light up.

3. When mains failure occurs or utility is abnormal, the generator will be controlled by the Control Box for

"Start-up Delay" automatic start.

4. When the generator has started and the voltage is normal, the "Generator Available" indicator lights up. If

the ATS automatically switches the generator on, and the "Generator On Load" indicator lights up.

5. When the utility is restored, the "Mains Available" indicator lights up. The ATS automatically transfers to the

mains side after the generator control box has sent the "Mains on Load" signal. The "Generator on Load" light

goes off and the "Mains on Load" indicator lights up.

6. When the ATS control box detects that generator voltage is normal, the "Generator Available" indicator

lights up. The ATS transfers to the generator side when the GCT time setting is set on conditions of "Generator

on Load".

instructions. Please contact us or the nearest dealer for help if faults are still unresolved.

1. The Main Switch has no action

A. The start-up delay has not nished. Please wait.

B. Verify whether the lines are correctly connected, especially the mains power source, the generator power

source, and load lines.

C. Check if the control lines from the ATS to the Control Box are correctly connected.

2. Indicators do not work

A. Verify whether lines are correctly connected or not, especially the mains power source, the generator power

source, and load lines.

B. Check if the setting of each control panel delay potentiometer is correct.

3. Generator does not start in case of utility outage

• DIN Rail mounted

• No DC supply required

• Adjustable MCB and GCB delays

• 10A/250V AC MCB and GCB outlets

• 10A/28V DC/250V AC remote start output

OPERATION

When the mains exist while all its phase voltage are below the limit 1/

• If R, MC, RST LEDs are on.

• The MCB terminal is supplied with voltage R.

• The REMOTE START relay contact is open.

• The REMOTE START relay contact opens.

If any phase voltage of mains is over the limit

• R, MC, RST LEDs turn off.

• The MCB terminal is open.

• The REMOTE START relay contact closes.

The REMOTE START output is expected to provide a generator set running condition.

When the generator set voltage G is over the limit
